Parking lights stay on

I came home today, parked shut the car off.
I was in the driveway working on another vehicle and I looked over and noticed my parking lights were on. I double checked the ignition, and it was off... took the key out of the ignition, pressed the park lights button. When I pushed the button the dash lights went out, but the parking lights stayed on. I tried the security button, and I ended up disconnecting the neg terminal on the battery. The tail lights are lit when the parking lights are on.
Anybody ever come across this? Where should I start looking for a problem?
Thanks in advance for any help or insight.
